I think how carcinogenic a thing is, how the thing is delivered, and what the thing is replacing, if anything, all matter, along with a hundred other factors. A highly carcinogenic habit that is addictive is morally much worse than a potentially carcinogenic sugar replacement, especially when you consider diabetics exist.
I'm not trying to judge your choices (I've smoked cigarettes at times), I'm just taken aback.
[edit: you can phrase your question differently. I won't be offended and I'm happy to explain my view on it.]
"foie gras are a few of the things that make it worth living"
... you know what they do to the duck to make your foie gras, right?
Worrying about that makes you a victim of the same fallacy.
You don't need to point out a vaguely defined group as bad or wrong. The same way "they" do it to look down on "you", that statement is "you" looking down on "them".
In both cases, it's a moot observation.
If it's because of some objective observation about that specific individual displayed over the course of the discussion, then your musings about some greater pattern or group are moot. If it's anything else, then you're the one not engaged in a good faith conversation.
And I do see how, if you've committed to being a smoker, reducing your risk and planning for the worst makes total sense. "I don't need to live past age 60" does sound a lot like passive suicidal ideation, and it may be worth speaking to a professional about it, but that's all I'll say on the matter, I don't want to be intrusive.
[I want to disclaim this as jawboning, I end up quiting smoking weed in this story, but I don't mean to imply anything by it and I understand quitting weed and quitting tobacco are worlds apart anyhow.]
I don't smoke tobacco anymore, but gosh I do love to smoke cannabis. I love the ritual of it, I love passing a bowl around with friends and listening to music, I love the texture of smoke, I love blowing smoke rings. It also helped to manage my anxiety. If I was having a panic attack, I could reliably terminate it by smoking. And it turned down the volume on the the anxious thoughts that I have bouncing around my brain.
Recently I've had episodes of terrible GI symptoms. Enough to briefly put me in the hospital. I'm not entirely sure, because many of the symptoms don't fit, but I think I've developed Cannaboid Hyperemesis Syndrome with an unusual presentation, the only cure for which is to quit using cannabis.
But I'm okay with it. By the time I came to this conclusion, I was making sure my will was in order, I just didn't know what was happening to me. So I was just happy that the best hypothesis seemed to be something curable.
So far, I haven't had an episode in a few days, the last episode I did have was milder. I'm starting to have more energy and feel like I just be thinking more clearly. The anxious thoughts that I smoke weed to treat are coming back strong, which has been difficult, but I'll find some other way to manage them.
I'll miss cannabis dearly, it served me well for a long time. I'm hoping I can smoke once a year at least. But man, I will do anything not to have an episode like that again.
Here's to the gift of life.
My friend who had terrible eating habits before (fried fish and chips daily) has discovered making his own pot edibles and the enjoyment of growing his own arugula salads. I think we work with what we've got, and we've got less to work with as we get older. There's no contradiction between wanting to live and wanting to enjoy life. Wanting to smoke or not caring if I live past 60 isn't a death wish - it's an affirmation to myself that I'm alive in the moment and not living in fear of age or death.
It's not black and white. Morality is a continuum of cause and effect.
Shooting someone is bad. Shooting bullets recklessly and accidentally hitting someone is bad, but less so. Shooting a bunch of bullets safely but leaving the lead in the ground to leach into a neighboring properties well is bad, but lesser still. Etc.
There are moral consequences to literally everything you do, it's just a matter of each individual's threshold for caring, and the social contract formed when people become part of a group. Some people care about the first and second order effects of smoking (increased burden on healthcare, land use competition, agricultural pollution, microplastic pollution, etc.) and some don't.
Does morality not apply to adults? Are adults immune to human psychology?
Tobacco stands out above others as being a very strong, addicting carcinogen.
It's specifically the nicotine in tobacco that is somewhat addictive. But nicotine isn't generally considered to be a carcinogen by itself.
Nick Naylor: Oh, this from a Senator who calls Vermont home.
Senator Lothridge: I don't follow you, Mr. Naylor.
Nick Naylor: Well, the real demonstrated #1 killer in America is cholesterol. And here comes Senator Finistirre whose fine state is, I regret to say, clogging the nation's arteries with Vermont Cheddar Cheese. If we want to talk numbers, how about the millions of people dying of heart attacks? Perhaps Vermont Cheddar should come with a skull and crossbones.
Senator Finistirre: That is lu --. The great state of Vermont will not apologize for its cheese!
Senator Lothridge: Mr. Naylor, we are here to discuss cigarettes -- not planes, not cars -- cigarettes. Now as we discussed earlier these warning labels are not for those who know but rather for those who don't know. What about the children?
Nick Naylor: Gentlemen, it's called education. It doesn't come off the side of a cigarette carton. it comes from our teachers, and more importantly our parents. It is the job of every parent to warn their children of all the dangers of the world, including cigarettes, so that one day when they get older they can choose for themselves. I look at my son who, was kind enough to come with me today, and I can't help but think that I am responsible for his growth and his development. And I'm proud of that.
Here's how they define items in group 2B:
> This category is used for agents for which there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. It may also be used when there is inadequate evidence of carcinogenicity in humans but there is sufficient evidence of carcinogenicity in experimental animals. In some instances, an agent for which there is inadequate evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals together with supporting evidence from mechanistic and other relevant data may be placed in this group. An agent may be classified in this category solely on the basis of strong evidence from mechanistic and other relevant data.
